IMPROVEMENT IN GREASE-CUPS.

Specification forming part of Letters Patent No. 49,259, dated August 8,1865.

To all whom 'it may concern.-

Beit known th at I, GERHARD HAGENMEYER, of Big River, in the county of Mendocino and State of California, have invented a new and Improved Grease-Cup; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to fully understand and construct my invention, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure l represents a vertical central section of my invention. Fig. 2 is a horizontal section of the same, the line .r w, Fig. l, indieating the plane of section.

Similar letters of reference indicate corresponding parts in the two figures.

This invention consists in the application of two valves connected together by a jointed stem, which can be easily lengthened or shortened, in combination with two seats, one above and the other below the bulb or reservoir of the grease-cup, in such a manner that by turning the handle attached to the valve-stem in one direction the lower valve is closed and the upper valve opened ready to admit the lubricatin g material from the receivingcup into the bulb, and by turning said handle in the opposite direction the upper valve is closed and the lower valve opened and the interior of the bulb broughtin communication with the steamcylinder or other device to be oiled. In order to allow the steam and air contained in the bulb to escape when it is desired to introduce thelubricating material into the same,itis provided with a spring-valve which will open by a slight pressure of the hand, and when released close bythe action of a sprin g combined with that of the steam in the interior of the bulb.

A represents the bulb of my grease-cup, which can be made of brass, composition, or of any other suitable material and inany desirable form or shape. This bulb is provided with a screw-shank, a, to screw into the steam-cyl inder, steam-chest, or other part to be oiled. Said screw-shank is bored out, as shown in Fig. 1 of the `drawings, so that a channel, b, is formed leading from the bulb to the cylinder or other part to be oiled. The lower part of the channel b is bored out larger than the upper portion, thus forminga shoulder or seat, c, for the lower valve, B. The stem C of this valve passes through the upperpart of the channel b, and it is tinted to allow the liquids l through the cup D, and mounted on its end is i the handle E.

The cup D is intended to receive the lubri eating material, and its shank e is` provided with a screw-thread to screw in a suitable socket in the upper end of the bulb A. Said shan-k is bored out to ad mit the stem C of the upper valve, and its lower end forms the seat c ior the valve B. The stern C is also tinted the same as the stem C, to allow the lubricating material to pass down into the bulb without obstruction.

The valve B is. provided with a notch, f, in its lower edge, and through this notch passes a pin, g, so that said valve can readily rise and fall, but is prevented from turning.`

1f the handle is turned in the proper direction, so that the valve B' will uuscrew from the stem C, the valve B is depressed on the pin gand the valve B is forced up in its seat. In this position the channel b, leading from the bulb A to the cylinder or other part to be oiled, is opened, the steam contained in -said cylinder or other article passes up into the bulb, soV

as to equalize the pressure and allow the lubricating material to descend by its inherent gravity.

If itis desired lo charge the bulb with grease,

the handle is turned in the opposite direction, so that the valve BI screws down on the stem C, the valve B is first drawn up in its seat and held thus by the pressure of the steam, and then by screwing a little further in the same direction the valve B' is made toileaveitswseat and the communication betweenftheJbulband cup D is open. y f f1.

The steam contained in the bulbis allowed to escape through a vent-hole, IL, which is closed by a spring-valve, i. By pressing on` thebut-` tonj, which is secured to the stem ot' this valve, the vent-hole h is opened and the air and steam are allowed to escape from the bulb,

and the lubricating material descendsl in to the same without obstruction.

This oiLcup is very simple in it construction, the valves are easil)7 kept tight, and it can be operated with the greatest facility.

What I claim as new7 and desire to secure by Letters Patent, is-

The arrangement of the valves B B7 the stems C C', the sets c c', bulb A, cup D, and vent-hole valve i, in the manner :md for the purpose substantially as herein shown and described.'
